Answer:
27 cubic millimeters
Step-by-step explanation:
Remember that a cube's surface area is 
where 
is any side length of the cube.
Hence, by solving 
, we find that the side length of a cube is 3 millimeters.
This means that the volume of the cube is 
Answer:
x=8
Step-by-step explanation:
This is a congruent triangle. If we use Pythagorean theorm, we can see that 3^2+y^2=25
y^2= 16
y=4
(y is the base of the small triangle)
and since the big triangle and the small triangle are congruent(the ratios are the same), 3 is half of 6, and so the base of the small triangle is half of the big triangle's.
4*2=8
x=8
Answer:
the formula to use is R = 100I/ PT
Step-by-step explanation:
R = rate, I = interest = $1100, P = $ 1000, T= 5years
<em>(x - 7)(x - 5)</em>
- <em>Step-by-step explanation:</em>
<em>x² - 12x + 35 =</em>
<em>= x² - 5x - 7x + 35</em>
<em>= x(x - 5) - 7(x - 5)</em>
<em>= (x - 7)(x - 5)</em>
